DEVICE FOR .MAKING: REENFORCING WEB.

Application filed January15, 1921. Serial No. 437,509.

To aZZ 107mm it may concern:

Be it known that l, KURT NossAcK, a citi- Zen of the German Empire, residing at (lottbus, Germany, have invented certain new and useful improvements in Devices for Making .lleentorcing Vl eb, oi which the following is a specification, for which it have filed applications in Germany on Apr. 18, 1915, and. 0ctober 12, 1920.

My invention relates to the manufacture of a web or netting serving for filling and '(?("1]l 1'tfllll' plaster work on ceilings and walls and this more particularly to the kind in which each lease or weave or crossing is embedded in a button or other shape oi clay, loam, cement or the li re. Now when manufacturing such a filling net, the net and the plastic material (clay or loam, etc.) are caused to run conjointly between twopattern cylinders, and when the lease passes through the centre of the mould, at the point where the space between the cylinders is the narrowest, the button is moulded around it.

However, the plastic material which when filled into the mould always chokes to a certain extent, now tends to draw the threads into the mould, as a result of whichaccording to the thickness of the thread and the width of the mesh, there will be produced a more or less considerable bulging, an irregular covering and, as a further conse quence, a crumbling off or the weaker side.

This defect is remedied, in accordance with my invention, by the arrangement within the centre of each half or section of the mould of a stamp-like elcvationwhich during the moulding operation acts as an abutment for the lease. By these means the threads, which in general are of wire, will now be prevented from being crushed and the'envelop or cover thereon will become uniform. its a result, provided the width of the mesh remain the same as that used for filling webs of this type as hitherto known, a weaker wire may be employed than that hitherto customary or wherever it is preferred to use a wire of the same grade, then the filling webs may be made with a larger width of mesh, preferably one of 25 mm. instead of 20 mm. as up to the present. It will be readily understood, that by these means there will be secured a considerable saving in wire during the manufacture of the web. To conclude, the web need not be made of wire, but-it may also be made of threads of any suitable kind.

. An additional feature of my invention resides in the patterns being given a circular or ring-shaped outline by the pattern cylinders, so that buttons made in accordance with my invention will no longer possess a cross shape, as hitherto, but will have the shape of a disc or ring. By so shaping, both the filling web as also the pattern cylinders, the advantage is secured that themanufacture of the cylinders will henceforth be substantially simplified, in'that the circular depressions formed therein may be made by drilling. As regards the stamp-like elevations arranged within the depressions they may be secured in a very simple manner by driving small pins or studs into the cylinders. y

In the drawings ailixed to this specification and forming part thereof, a device and product embodying my invention are illustrated by way of example. In the drawings,

Fig. 1 is a plan of part of a pattern cylinder bearing the moulds for the buttons, I

Fig. 2 is a cross sectionof part of a pair of cooperating cylinders.

Fig. 3 is a plan view of a section of the finished article, while i i Fig. 4- is a cross sectionon line IV-IV in Fig. i

Referring to the (.lrawings, u. are the cavities or dies formed in the uppersuritace of the cylinder 7). In the centre of each cavity a there is a raised portion 2' which is either integral with the cylinder or may consist of a stud or pin inserted into the cylinder. The cylinders are in addition provided with grooves disposed at right angles to each other and intersecting at the raised or elevated points '2', these grooves serve as guides for the threads of the web, the grooves 0 being destined for the woof threads 0 and grooves (Z for the warp threads j. Additional. pins g arranged on the cylinders and adapted to lodge themselves in suit able holes 7i formed in the counter cylinder, serve'to take the web along in thecourse of the manufacturing process.

The stamp-like raised portions i arranged within the depressions or cavities a produce as shown in Figs. 8 and l, crater or cupshaped depressions Z5 the buttons a. and

that on both sides thereof, notwithstanding the stamp-like elevated portions 2 are only of such a. height that the Wires 6 and f will not be entirely uncovered Within the buttons, but that above these Wires there will still remain a thin layer of material. The cratershaped depressions on both sides of the filling web increase the degree to which the plaster is supported and secured by the Web in that when making the plaster surface, plaster Will come to enter these depressions and will thus cause a short plug of mortar to be formed therein.

As shown in Figs. 3 and 4c, the filling Web made by aid of the cylinder disclosed in Figs. 1 and 2, is provided with buttons or other shaped bodies 0/ made of burnt clay, loam, cement or the like, having the shape of a double cone truncated at both its sioes, and provided on either face with the aforesaid cup-shaped depressions. ll hen given their maximum circumference, these buttons or shapes will be so large, that they almost come to touch tubular connections 0', 01 oi the same material as the buttons serving to cover the sections of the Wires 0 and f disposed intermediate said buttons.

The term button as used in the appended claims is meant to comprise every kind of suitable shape adapted to serve the sane purpose.

I claim:

1. In a tissue coating device in co1nbination, a mould comprising a plurality of substantially cup shaped cavities in spaced relation to each other, thread engaging means between said cavities and intersectingly grooved, substantially knob shaped projections in said cavities.

2. In a tissue coating device in combination, a mould. comprising a plurality of substantially circularcup shaped cavities spaced from each other, and. intervening raised thread engaging portion between said cavities, and a. substantially.lrnob shaped superficially intersectingly grooved projection in said cavity of less height than the interveir' ing raised portion.

3. In a tissue coating device in combination, a pair of cooperating confronting and si moulding rollers, a plurality oi? intercrossingly arranged rows of substantially cupshaped adjacent disposed cavities on said rollers raised thread engaging port-ions intermediate the cavities of each roller and spaced from the thread engaging portions of the opposite roller, and a substantially knob shaped superficially intersectingly grooved projection in each cavity of less height than the thread engaging portions.

l. In a tissue coating device in combination. a pair of cooperating confronting moulding rollers, a plurality of intercrossingly disposed. rows of substantially cir =i lar, cup shaped adjacently arranged cavities on said rollers, raised thread engaging portions between the cavities of each roller and speed from the threiul portions 01 the opposite roller, and a substantially knobshaped superficially intercrossingly grooved n'ojcction in each cavity oi less height than the thread engaging portions and intei engaging ltnob and socket members on one side said raised threznl engaging portions ot the rollers.

5. ln a tissue coating device in. combination, a mould comprising a plurality of substantially circular cavities adjacently arranged, grooved thread engaging raised nortions between said cavities, a substantially knob shaped rounded. superficially intercrossingly grooved projection in each cavity and knob and socket members on one side of salt thread engaging raised portions.

6. In a Wire-tissue coating do ice in combinscion a pair of controntii y arranged cooperating moulds, a phiralitr of intercross y arranged rows of substantially circular cup shaped cavities in said moulds, raised thread ing superf cially grooved connec ing pm... 0. s between said cavities.

iostantially,rounded knob shaped snpe'" ally intcr-crossiugly ground projections in said cavities of less height than said thread Cl portions, inter-engaging guiding pins aml holes oppositely arranged at one side of. said raised thread engaging portions. I
